This application claims priority from and the benefit of U.S. Provisional Patent Application Ser. No. 61/571,506, filed Jun. 29, 2011 (titled “Cool blade 4×4”), the entire contents of which are hereby incorporated by reference.

This invention relates to one or more devices, systems, and methods of an in-line skate configured to move on multiple types of terrain and surfaces. Specific examples of embodiments of this invention relate to a first coupler device and/or a second coupler device for coupling one or more wheels on at least one of the front end and the back end of the in-line skate. The first coupler device and second coupler device allow the in-line skate to be capable of moving over diverse types of terrain and surfaces.

BACKGROUND OF THE INVENTION

An in-line skate is a type of roller skate. A typical roller skate (or quad skate) has two horizontal wheels in front and two horizontal wheels in back of the bottom of a boot with a front stopper and/or a back stopper. A typical in-line skate has two, three, four, or five wheels configured in a single-file line (or linear line) on the bottom of the boot with (or without) a front stopper and/or a back stopper. Each of the wheels of a typical in-line skate are the same size (e.g., from about 30 millimeters to about 70 millimeters in diameter). A popular brand of in-line skates is Rollerblade®.

In-line skates are designed to move on smooth surfaces. For example, an in-line skate is designed to move, roll, or otherwise travel over an arena floor, a cement sidewalk, a paved road, a smooth bike path, or other smooth and even surface. However, moving, rolling, or otherwise traveling on an uneven surface (e.g., grass, gravel, dirt, rocks, mud, snow, ice, or other) using an in-line skate is nearly impossible. On these uneven surfaces, the wheels of the in-line skate are not able to freely rotate, so the user of the in-line skate will slow-down, stop, fall, topple over, or otherwise lose control.

The present invention of an in-line skate adds one or more coupler devices and third, fourth, fifth (or more) wheels. The coupler devices and third, fourth, fifth (or more) wheels of the present invention vary in size and shape to provide stability to the in-line skate. The present invention configures the in-line skate, so that it is able to move, roll, or otherwise travel over smooth and uneven surfaces without causing the user of the in-line skate to slow-down, stop, fall, topple over, or otherwise lose control while using the in-line skate. The addition of the coupler devices and additional wheels to an in-line skate, particularly at the front end and/or back end of the in-line skate provides stability and easy rotation of the wheels over various surfaces. The present invention gives the user of the in-line skate more support to his/her ankles because the center of gravity of the user using the first coupler and/or second coupler of the present invention is lower compared to a typical in-line skate. The present invention allows the weight of the user to be split between the extra wheels at the front end and/or back end of the in-line skate (which makes the center of gravity of the user lower than the front end and/or back end of the in-line skate).

DETAILED DESCRIPTION

The present invention includes a first coupler device and/or a second coupler device for coupling one or more wheels onto at least one of the front end and the back end of the in-line skate. The first coupler device and second coupler device allow the in-line skate to be capable of moving over diverse types of terrain and surfaces. The one or more coupler devices of the present invention can be used for an in-line skate that is “all-terrain” or can move, roll, rotate, or otherwise travel on uneven surfaces. The one or more coupler devices of the present invention can be used with bicycles, skis, and other sports equipment, so that the coupler device allows for attachment of stabilizing devices (wheels, anchors, or other devices) to the sports equipment.

The present invention adds one or more coupler devices and/or one or more additional wheels to an in-line skate, for example, at the front end and/or back end of the in-line skate. The coupler device and/or additional wheel adds stability to the in-line skate, so that the in-line skate can travel over most surfaces (including roads or sidewalks with cracks or bumps, gravel roads or walkways, mountain trails, rocky mountain trails, sand, grass, hills, ice, slushy roads, dirt, mud, or other). By adding the coupler device and/or additional wheel, the center of gravity of the user of the in-line skate is shifted lower. This lower center of gravity provides stability to the user. In addition, varying the size of the one or more coupler devices and/or one or more additional wheels added to the in-line skate allows the in-skate to be used on many diverse and uneven surfaces (that typical in-line skates cannot be used on). The user is less likely to lose balance, fall, or topple over (such as while skating over a pothole or cracks in the road or other surface).

In accordance with an exemplary embodiment of the present invention, as illustrated in FIG. 1, FIG. 2, FIG. 3, FIG. 5, FIG. 7, FIG. 9, FIG. 11, FIG. 13, FIG. 15, and FIG. 16, a first coupler device 111 is configured to couple to the frame 103 of the in-line skate device 100.

Optionally, the in-line skate 100 includes a first coupler device 111 coupled to a front end 112 of the frame 103. Optionally, a second coupler device 113 can also be coupled to the front end 112 of frame 103 (e.g., to securely couple (or sandwich) around frame 103) via one or more holes 103a. Coupling or sandwiching the first coupler device 111 and the second coupler device 113 around frame 103, such as with one or more bearings 110 and one or more axles (or axle bolts) 108 (and one or more axle nuts 133) via one or more holes 103a, securely connects the first and second coupler devices 111 and 113 to frame 103. The bearings 106 allow the wheels 105 of the in-line skate 100 to rotate freely. The axles 109 can be a common axle, a screw, a bolt, a quick-release bolt, or any other type of attachment for connecting the wheels 105 to the frame 103.

Optionally, the in-line skate 100 includes a third coupler device 115 coupled to a back end 116 of the frame 103 via one or more holes 103a. Optionally, a fourth coupler device 117 can also be coupled to the back end 116 of frame 103 via one or more holes 103a (e.g., to securely couple (or sandwich) around frame 103). Coupling or sandwiching the third coupler device 115 and the fourth coupler device 117 around frame 103, such as with one or more bearings 106 and one or more axles (or axle bolts) 104 (and one or more axle nuts (not shown)), securely connects the third and fourth coupler devices 115 and 117 to frame 103. One or more of first, second, third, and fourth coupler devices 111, 113, 115, 117 can be coupled to (or sandwiched around) frame 103, for example on the front end 112 and/or the back end 116 of the frame 103, so that the first, second, third, and fourth coupler devices 111, 113, 115, 117 can be anchored to frame 103. The axles 104 can be a common axle, a screw, a bolt, a quick-release bolt, or any other type of attachment for connecting the wheels 105 to the frame 103.

The first coupler device 111 and/or second coupler device 113 are coupled to a front wheel 119 via one or more bearings 110 and axles 108, so that the front wheel 119 is securely anchored to frame 103. See FIG. 2. The third coupler device 115 and/or fourth coupler device 117 are coupled to a back wheel 121 via one or more bearings 106 and axles 104, so that the back wheel 121 is securely anchored to frame 103. See FIG. 2. The axles 108 can be a common axle, a screw, a bolt, a quick-release bolt, or any other type of attachment for connecting the front wheel 119 to the first coupler device 111 and/or second coupler device 113. The axles 104 can be a common axle, a screw, a bolt, a quick-release bolt, or any other type of attachment for connecting the back wheel 121 to the third coupler device 115 and/or fourth coupler device 117. The front wheel 119 can be used alone, the back wheel 121 can be used alone, or the front wheel 119 and the back wheel 121 can be used together. Depending on the activity of the user of the in-line skate 100, various combinations of using the front wheel 119 and/or the back wheel 121 may be beneficial.

The front wheel 119 and the back wheel 121 can vary in size depending on the surface on which the user would like to move, roll, climb, otherwise traverse. For example, the front wheel 119 and the back wheel 121 can range in size of diameter from 1 inch to 25 inches (and in all increments of these sizes). For example, the front wheel 119 and/or the back wheel 121 can be 5 inches in diameter. Using a varying size wheel for the front wheel 119 and/or the back wheel 121 (such as 5 inches or various other sizes) stabilizes the user while using the in-line skate 100. In turn, this can provide a more smooth ride and substantially prevent the user from slowing-down, stopping, falling, toppling over, or otherwise losing control (e.g., even while traveling on uneven surfaces (potholes, cracks, gravel, dirt, sand, or any other surface)).

Varying sizes of first, second, third, and fourth coupler devices 111, 113, 115, 117 are illustrated as item 131a, 131b, 131c, 131d, . . . 131n (where n is any number or letter) to illustrate using these frames with varying size front wheel 119 and/or back wheel 121 (depending on the activity of the user and the surface on which the user is moving). The coupler device 131d has an angled piece 132, which can be angled out in the z direction in order to accommodate front wheel 119 and/or back wheel 121 (that is wider than typical wheels). Each of the coupler devices 111, 113, 115, 117 can be an embodiment of coupler device 131d with the angled piece 132, so that coupler devices 111, 113, 115, 117 can be further adjustable for differing size wheels 119/121. For example, the angled piece 132 of the coupler device 131d can be angled out in the z direction, so that it is wider in the z direction near wheel 119/121 and narrower (in comparison) near where the coupler device 131d attaches to frame 103. For example, the angled piece 132 can be angled out in the z direction at about 1 degree to 90 degrees. The angled piece 132 is illustrated on the right side of hole 111b (or 113b, 115b, or 117b); however, the angled piece 132 can be on the left side of the hole 111b (or 113b, 115b, or 117b). The angled piece 132 can also be on the right side or left side of hole 111c (or 113c, 115c, or 117c). Configuring the coupler devices 111, 113, 115, 117 with the angled piece 132 can eliminate the need for using one or more washers or spacers to be able to accommodate differing size front wheel 119 and/or back wheel 121. It may be preferable to use coupler devices 131a, 131b, or 131c (without the angled piece 132), where the need still exists to have a wider than usual front wheel 119 and/or back wheel 121. In such an embodiment, one or more washers or spacers (not shown) can be coupled between one or more of the coupler devices 131a, 131b, and 131c and the frame 103 to maintain a relatively straight coupler device 131a, 131b, and 131c (without the angled piece 132) while accommodating for the wider than usual wheel 119/121. The one or more washers (or spacers) can be of varying sizes and thicknesses depending on the size of the wheel 119/121. The angled piece 132 can be used with wheels 119/121 for the in-line skate 100 or for wheels on a bicycle, bike trailer, baby stroller, or any other type of wheel (e.g., with a bearing for coupling to frame/item 131d or coupler devices 111, 113, 115, or 117).

With reference to FIG. 1, FIG. 2, FIG. 13, FIG. 14, and FIG. 15, various sizes of the front wheel 119 and/or the back wheel 121 can be used. In some cases, one size may work better on roadways or uneven rough roads (e.g., a 5 inch wheel in diameter or a 7 inch wheel in diameter). In other cases, another size may work better on potholes in a road or large cracks in a sidewalk (e.g., a 7 inch wheel in diameter or a 9 inch wheel in diameter). Still in other cases, another size of the front wheel 119 and/or the back wheel 121 may work better depending on the activity the user is participating in (e.g., any diameter ranging from ½ inch (or less) to 30 inches (or more)). A coupler device 129 (in FIG. 1) includes one, two, or more holes on an end 129a that connects to the wheel 119/121. The end 129a can be in an oblong shape to accommodate one, two, or more holes. The holes can be a distance of about ¼ inch to about 1 inch (or more) depending on the adjustability desired for connecting to the wheel 119/121. These holes on the end 129a allow for further adjustability and varying size wheels 119/121 when connecting the coupler device 129 to wheel 119/121 (e.g., to adjust the height of the wheels 119/121 for going over bumpy surfaces and varying terrain).

In FIG. 3, a hole 115a on the coupler device 115 is elongated in the x direction (and/or the y direction), so that the frame 115 can connect at various points along the x direction (and/or the y direction) at the hole 115a with frame 103. This adjustability allows for varying size wheels 119/121 to attach to the frame 103 via the coupler device 115. Similarly, a hole 117a (not shown in FIG. 3) on the coupler device 117 is elongated in the x direction (and/or the y direction), so that the frame 117 can connect at various points along the x direction (and/or the y direction) at the hole 117a with frame 103. In FIG. 5, FIG. 7, FIG. 9, FIG. 11, FIG. 13, and FIG. 15, a hole 111a on the coupler device 111 is elongated in the x direction (and/or the y direction), so that the frame 111 can connect at various points along the x direction (and/or the y direction) at the hole 111a with frame 103. This adjustability allows for varying size wheels 119/121 to attach to the frame 103 via the coupler device 111. Similarly, a hole 113a (not shown in FIG. 5) on the coupler device 113 is elongated in the x direction (and/or the y direction), so that the frame 113 can connect at various points along the x direction (and/or the y direction) at the hole 113a with frame 103.

In FIG. 5, FIG. 7, FIG. 9, FIG. 11, FIG. 13, and FIG. 15, the coupler devices 111 and 113 can include one or more additional holes 111b and 113b, so that frames 111 and 113 can connect with frame 103. The coupler devices 115 and 117 can include one or more additional holes 115b and 117b, so that frames 115 and 117 can connect with frame 103. The coupler devices 111 and 113 can include one or more additional holes 111c and 113c, so that coupler devices 111 and 113 can connect with the front wheel 119. The coupler devices 115 and 117 can include one or more additional holes 115c and 117c, so that frames 115 and 117 can connect with the back wheel 121.

In some embodiments, a wheel with a diameter of 10 inch, 12 inch, or 16 inch for the front wheel 119 and/or the back wheel 121 may travel well for all-terrain activities (e.g., where the surfaces on which the user is using the in-line skate 100 may vary during the activity (sidewalk, then grass, then gravel, then dirt, then back to sidewalk, and so on)). In one embodiment, the front wheel 119 and/or the back wheel 121 can be a bicycle wheel (such as a mountain bike wheel and tire capable of traveling through all-terrain surfaces). If the front wheel 119 and/or the back wheel 121 is a mountain bike wheel and tire, then the in-line skate 100 can be ridden down large hilly mountain trails (with uneven surfaces, varying turns, and varying obstacles to traverse).

In some embodiments, 10 inch, 12 inch, 14 inch, 16 inch, 18 inch, or larger wheel in diameter for the front wheel 119 and/or the back wheel 121 can be used. For example, the front wheel 119 and/or the back wheel 121 can be a flat rubber, such as an automobile wheel and tire. This type of wheel can travel on most surfaces including roads, sidewalks, gravel, grass, snow, sand, and hills (over roads, sidewalks, gravel, grass, snow, and sand). For example, the front wheel 119 and/or the back wheel 121 using a flat rubber (wheel without air) can travel over slush, ice, mud, and other uneven surfaces and during varying weather conditions. In addition, since such a wheel does not have any air, even if it punctures, rips, tears, or otherwise deforms, the wheel can still be used in whatever activity the user is doing.

The in-line skate 100 can also include an optional brake or stopper (not shown) coupled to the front end 112 and/or the back end 116 of either the left or right boot 101. Alternatively, instead of the brake or stopper, the front wheel 119 and/or the back wheel 121 can be dragged on the ground or other surface to slow down the user or bring the user to a stop.
